State-of-the-art bipolar logic technology has advanced with the recent introduction of 'Super Schottky' and 'Low Power Super Schottky' product lines by two semiconductor manufacturers. Texas Instruments (T.I.) and Fairchild Semiconductor have utilized advances in processing techniques such as oxide isolation and refinements in the resolution of photolithographic equipment to enhance the speed and reduce the power of present day Schottky (S) and Low Power Schottky (LS) technologies. This report provides results obtained from the electrical characterization over the military temperature range (-55 CTj to + 125 CTj) of gate and flip-flop samples of three new transistor Transistor Logic (TTL) technologies; Advanced Schottky (AS), Advanced Low Power Schottky (ALS), and Fairchild Advanced Schottky (TTL) (FAST). This report shows that each technology offers the system designer unique advantages in terms of improved performance, power reductions, and space savings derived from functional design complexity. The performance improvements obtained by these new logic technologies, however, present implicit new application and testing considerations that could previously be ignored by the military system designer.
